CONVERTIBLE STOVE-OVEN.

lowing is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from' other inventions.

My invention pertains to a convertible stove oven appliance and more articularly to an alternative arrangement in the oven of the stove whereby, in the absence of a removable partition an extensible shelf structure may be supported across the entire width of the oven; and when a partition is in place the shelf structure embodying my invention may be adjusted to smaller compass so as to be accommodated within a division of the oven compartment.

My invention carries forward the idea represented by the Trenkamp Patent No. 1,355,868 and the pending.- application of H. J. Trenkamp, Serial No. 295,886.

Accordingly, the object of my invention is oven, convertible as to size, a shelf structure correspondingly alterable as to size and which shall be simple and economical to manufacture and the parts of which may be easily manipulated to their alternative relasmaller doors opened.

Application filed August 9, 1919. Serial No. 816,854.

Fig. VIII is an enlarged perspective view. of connections between certain of the parts of the shelf appliance.

The stove is shown supported on suitable legs 1 which carry a frame 2 which includes a bottom 3 and a partition 4 extending from front to rear thereacross and of limited hei ht. Supported in any suitable manner wit in the frame 2 is an oven compartment including a bottom 5 extending across the top edge of the partition 4, side walls 6 and a rear wall 7. It is common practice in the art to so space an oven compartment both from the actual bottom of the stove and from its inclosing walls so as to afford conduits entirely around the oven for the gases of combustion arising from gas burner below. I propose to place at least one gas burner on each side of the partition 4 and to provide means whereby each burner may be separately controlled. In consonance, two burners 8 and 9 are illustrated which are located between the bottoms 3 and 5 and on opposite sides of the partition 4. The supply of fuel to the burners 8 and 9 is controlled by suitable valves 10 and 11 respectively both of which open or close communication with a gas supply pipe 12.

The open front of the entire oven compartment is adapted to be closed by a large door 13 mounted below on suitable hinges 14 and provided with a handle 15. Two smaller doors 16 and 17 are each hinged at 18 and 19 respectively to the larger door 13 and they carry handles 20 and 21. Extending across the middle of the top and bottom of the oven compartment in a direction from front to rear are two pairs of angle irons 22 and 23 respectively each pair forming a suitable channel for the slidable accommodation of a removable partition 24 which is provided on opposite sides and at various hei hts with ledges 25 as clearly appears in ig. II. The side walls of the oven compartment are also provided with ledges 26 and 27 of corresponding elevation. to the ledges 25.

From the foregoing description it will be understood that when the partition 24 is in more than one half of the width of the oven.

straight line. The construction comprises two equisizedrectangular frames 28 and 29 each of which is of such a size .as to fit onehalf of the oven compartment, that is to say, slide freely between one of the side walls.

' and the partition 24 so as to rest on any appropriate pair of ledges. The frames 28 and 29 carry cross wires 30 and 31- respectively, which may, for example, be spot welded in place. It will be observed that there are seven Wire lengths 30 and seven 7 wire lengths 31 which will extend in a direction from front to rear when the shelf structure is in osition in the oven. As shown in Fig. that one of the wires 30 which is second from the end of the frame 28 which is nearest to the frame 29 is fashioned near each of its ends with a downwardly curved eye 32. Likewise, the second nearest wire 31 in the frame 29 is pro-' vided with a pair of downwardly bent eyes 33 as is clearly shown in Fi VIII. The eyes 32 and 33 are preferab y equidistant from the nearest edges of the frames 28 and 29.

The shelf appliance comprises in addition to the frames 28 and 29 a bracket also shown to be of wired construction. As shown in the drawings the bracket is permanently secured to the frame 28 and detachably connected with the frame 29. The bracket consists of two wrought iron side members 34 and 35 connectedby a pair of cross wires 36 and 37. One end of the side-member 34 is fashioned with'a hook 38 which is closed around the eye 32 as may be seen in Fig. VIII. The alined end .of the side member 35 is similarly fashioned with a hook 39 closed around the other eye 32. The opposite ends of the side members 34 and 35 are fashioned with opened hooks 40 and 41 respectively adapted detachably to engage with the eyes 33. Raised middle sections 42 and43 of the side members 34 and 35 correspond in length to the distance between the near edges of the frames 28 and 29 and substantially to the space required for the passage of the partition 24. In this manner the assembledshelf structurewhen extended may rest upon the ledges 26 and 27 as shown in Fig. III. Also, the tops of the raised sections 42 and 43 may thus be substantially level with the upper sides of the frames 28 and 29 and additionally form "a steadying abutment.

One of the wires 30 and specifically the second from the end of the frame 28 which is I farthest from the eyes is provided at its middle with a downwardly directed integral spring hook 44. Such hook is substantially the same distance from'that wire 30 which is vupon t eledges 25 and 26 as shown in Fig. II.

' s will now be readily understood the frame 28 together with its attached inutile bracket may act as a'shelf on the side of the partition 24 while the frame 29. serves as a shelf on'the opposite side. The assembled frames 28 and 29 may rest upon the ledges- 26 and 27 when the partition 24 is removed as appears in Figs. III and IV, in which position the adjacent edges of the frames 28 and 29 bear downwardly against the side members 34 and 35 about their hook and eye pivots. Fig. VII illustrates the position of the frames 28 and 29 which enables the engagement or disengagement of the eyes 33 by the hooks 40 and 41 whereby the alternative function of the whole may be realized.

I claim.

A device of the character described comprising a pair of shelves each provided a given distance from one end with a pair of eyes, and a bracket provided at each end with a pair of hooks adapted for movable engagement with said eyes respectively said bracket being adapted to underlie said shelves when brought into substantial alinement therewith and adapted when in such position to support such attached ends of the shelves in substantially the same horizontal plane when the other free ends thereof are supported, one pair of said hook and eye connections being detachable whereby said shelves may be separated, and means for fastening the end of said bracket thus freed to the shelf to which it remains attached.

2. The combination with a stove oven provided with ledges, a removable upright partition likewise provided with ledges, an adjustable oven shelf including a member of a size adapted to rest upon ledges on one wall of said oven andthe near side of said partition respectively, a bracket pivotally connected with one end of said member, and another member detachably connected with said bracket and of a size adapted to rest upon a ledge on the opposite wall of said oven and upon a ledge on the opposite-side of said partition, and a catch upon said. first mentioned member adapted to secure the free end of said bracket when said last mentioned member is detached, the .connected members and bracket together adapted to span the entire 4 oven and likewise provided on opposite sides with ledges adapted to be substantially level with said wall edges when said member is in its partitioning position, and a convertible shelf structure formed of a pair of separable parts adapted singly to rest each upon a distinct pair of wall and partition ledges, and adapted to be attached to each other so as to rest in substantially horizontal positions each with an edge supported upon one of said wall ledges when said member is not in its partitioning position.

4. A device of the character described comprising the combination of a stove-oven having oppositely disposed side walls provided with ledges, a removable partition provided on opposite sides with ledges substantially level with said wall ledges, a convertible shelf structure formed of a pair of separable parts each adapted singly to rest upon a wall and a partition ledge, and means rigidly connecting said parts in eX- tended relationship, whereby to enable support thereof upon said wall ledges when said partition is removed.

5.
